    Neither were you right that the FAQ doesn't treat it differently. Also, while 'funny' should be blatantly obvious, it actually gets an explanation twice.. you may not find that odd or goign to great length, considering the subject at hand, I do think it goes to great length to explain this.
    I didn't say that the FAQ doesn't treat funny differently, I said "In only one place in the FAQ is funny treated to more comprehensive explanation than other moderations". Read it carefully. Please don't make me quote that line to you a third time. Also note that it is an FAQ: all the positive mods are blatantly obvious, yet they get explained. Funny happens to get a couple of notes elsewhere pointing out that funny doesn't add karma. That's not "great lengths".
    The exact result of a single post you cannot judge, and I don't think karma should in any way be a major consideration. But when you are moderating anyway, you know that your actions will have some effect on others, and I really don't see any reason why that is wrong to keep in mind.
    I don't object to keeping it mind at all, although I don't see the point because you can't know what effect you're having. I do object to people switching from an accurate funny mod to an inaccurate interesting mod because you don't agree with the site owners' rules. If you're worried about reversing the effect of a down-mod, either contact an editor or assume it'll get dealt with in M2.

    Anyway I think we've about done this to death, so while I will read any reply you make, I probably won't reply myself. It's been a enjoyable discussion, thanks for that.

    Sice JDK 1.2 there is the strictfp declaration that can be applied on methods which needs the precicise IEEE floating point.
    I don't think you understand what strictfp means. You should have another read through that tutorial you linked to. strictfp means that arithmetic must be performed with all intermediate value conforming to IEEE 754 form. Not using strictfp allows the compiler/JVM some leeway in the handling of intermediate values - specifically intermediate values can use an expanded exponent range so that expressions that would overflow due to intermediate values overflowing no longer do so. For example, consider the expression 10*x*0.1. With strictfp the intermediate value 10*x must conform to IEEE 754 format and so can cause an overflow even though the final expression will not overflow. Without strictfp the compiler/JVM can optionally use an expanded exponent range for the intermediate value to prevent that overflow.

    strictfp has nothing to do with allowing alternative floating point formats to be used other than for intermediate values (and then only increased exponent ranges). The lack of strictfp will not permit implementations to use machine-native formats that do not produce identical results (including binary compatibility) to IEEE 754. It is not going to fix the floating point performance issues on x86.

    Just because two queries return the same results today do not mean that they will continue to do so in the future.
    You missed the parent's point here. The parent was meaning things like:

    select * from tab1 where exists (select 1 from tab2 where tab2.col1 = tab1.col1)
    versus
    select tab1.* from tab1, tab2 where tab1.col1 = tab2.col1
    These queries all return the same set of results in all cases, but may be excuted differently and perform differently.
    That's like trying to do math without a concept of zero. Sometimes, things just don't apply and we put "N/A" on the form and "NULL" in the database.
    The difference is that zero can be treated just like any other number in almost all cases. But in SQL, null cannot. It makes many queries much more complex for little gain. I've been dealing with RDBMSs and SQL for many years and I've come to the conclusion that null is evil, and in most cases we'd be better off without it.

    That's fine, of course, but not how this discussion started. It started with someone suggesting that modding a funny post insightful or interesting or whatever was the right thing to do because funny doesn't give the poster karma. My main problem with this is it means the comment reason modifiers I can set won't do what I want because some people are incorrectly categorising posts.

    That FAQ tells that funny was originally intended to work the same as any other 'judgement'. That was changed at a certain point, and ever since, there are people who refuse to moderate things funny when there is any alternative, draw your conclusion.
    My conclusion is that you're acting irrationally in trying to consider karma when you can't do so accurately anyway, and in making Slashdot a less ordered place (which is saying a lot really) by incorrectly categorising posts. I also conclude that some of your incorrect mods probably get flagged unfair in M2, which is as it should be. It's really very altruistic of you to be so worried about other users' karma that you'll put your own on the line.

    Lets get something very clear here, yes, the people who runt the site own the server, own the domain, and set the rules. They do not own the content.
    Who owns the content is completely irrelevant. You can't refuse to have your comments moderated, even though you own them. You can't have your comment removed, even though you own it (although I'm not sure if Slashdot's rules would protect the owners in court over this).
    Besides, if people would all agree on how to moderate, there would be little point in letting multiple people moderate the same post.
    Obviously people will disagree about whether a particular comment is interesting or whatever. However you're are talking about deliberately moderating incorrectly. That's a completely different story, and one which you have failed to justify to me (not that you need to, of course, but convincing the other person of your view is the seldom-achieved goal of debate, right?).

    No. Mods are not there to individually decide whether or a poster is a good one and should be able to post with the bonus (which is the sole point of karma, and the indirect effect of awarding it). Mods are there to judge an individual post. A mod doesn't have enough information to make the judgement anyway. For example, you don't know whether your's, or others' mods will actually affect a users karma - they may be at the cap, or a mod may be metamodded unfair.

    In the particular case of the funny mod, people are not supposed to get karma for merely being funny. A post is both funny and a troll, well the karma loss is something that poster should accept as the cost of posting that particular type of joke.

If a post is marked as troll when it's not that moderation will probably be flagged as unfair, and the poster will get their karma back (not that I understand why you're so hung up on this point of karma).
